This DS18B20 Temperature Sensor Module For Arduino, a Digital temperature sensor DS18B20 will tell you, with 9 to 12-bit resolution! Uses only 1 wire to the Arduino or other micro-controller for communication. With the One Wire protocol, you can operate a large number of these sensors from one Arduino pin.

This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports °C with 9 to 12-bit precision, -55°C to 125°C (+/-0.5°C). Each sensor has a unique 64-Bit Serial number etched into it allows for a huge number of sensors to be used on one data bus.

This is a wonderful part that is the cornerstone of many data-logging and temperature control projects.

Features :

  1. Unique 1-Wire interface requires only one port pin for communication
  2. Each device has a unique 64-bit serial code stored in an onboard ROM
  3. Multidrop capability simplifies distributed temperature sensing applications
  4. Requires no external components
  5. Thermometer resolution is user-selectable from 9 to 12 bits
  6. Converts temperature to the 12-bit digital word in 750ms (max.)
  7. User-definable nonvolatile (NV) alarm settings
  8. Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
  9. Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system
